class_docstr: Extract raw HTML from text.
  
  The raw HTML is stored in the [`htmlStash`][markdown.util.HtmlStash] of the
  [`Markdown`][markdown.Markdown] instance passed to `md` and the remaining text
  is stored in `cleandoc` as a list of strings.
code: def parse_bogus_comment(self, i: int, report: int = 0) -> int:
      # Override the default behavior so that bogus comments get passed
      # through unaltered by setting `report` to `0` (see #1425).
      pos = super().parse_bogus_comment(i, report)
      if pos == -1:  # pragma: no cover
